嗨，我是 python 和脚本的新手，阅读了很多教程并尝试创建脚本以将 curveShapes 组合成一条具有多形状的曲线，这对我来说很好。但是在这里我有一个错误，当我在启动 Maya 后第一次启动脚本时，它会给我回溯，如果它运行一次，它不会给出任何错误或回溯：

// Error: Not enough objects or values.
# Traceback (most recent call last):
#   File "<maya console>", line 2, in <module>
#   File "C:/Users/.../maya/2017/scripts\CreateOneCurve.py", line 17, in <module>
#     cmds.parent(r=True, s=True)
# RuntimeError: Not enough objects or values. //

这是我的脚本：

#Funcion for create list of objects
def listCurveObj():
    shapeList = cmds.ls(cmds.listRelatives(s=True), s=True)
    groupList = cmds.ls(cmds.group(em=True, n='Curve#'))
    listAllobjects = []
    for obj in groupList:
        listAllobjects.extend(shapeList)
        listAllobjects.extend(groupList)
    return listAllobjects

#Create one Curve
cmds.select(listCurveObj())
cmds.parent(r=True, s=True)

#Clean scene
transforms =  cmds.ls(type='transform')
deleteList = []
for tran in transforms:
    if cmds.nodeType(tran) == 'transform':
        children = cmds.listRelatives(tran, c=True) 
        if children == None:
            print '%s, has no childred' %(tran)
            deleteList.append(tran)

if len(deleteList) > 0:            
   cmds.delete(deleteList)

有人可以帮忙吗？

嗨，我试图用 pymel 解决我的问题并重做，所以现在我的第一部分工作完美：

import pymel.core as pm

#Get list of objects
shapeList = pm.ls(pm.listRelatives(c=True))
groupList = pm.ls(pm.group(em=True, n='Curve#'))
listAll = []
for obj in groupList:
    listAll.extend(shapeList)
    listAll.extend(groupList)

#Parent objects to one Curve
pm.select(listAll)
pm.parent(r=True, s=True)

但是第二个（干净的场景）不起作用，所以我认为在这里我无法列出，我不知道如何接收空组列表或如何比较两个列表并删除相同的项目？

看起来像是过杀了，为什么不这样呢？

import maya.cmds as mc

def combineCurves(curves = []):
    crvGrp = mc.group(n = curves[0], em=1)
    for crv in curves:
        crvShape = mc.listRelatives(crv, shapes = 1)
        mc.parent(crvShape,crvGrp,s=1,r=1)
        mc.delete(crv)
        
combineCurves(mc.ls(selection=1))

您好，现在我解决了所有的错误和警告并完成了我的第一个 python 脚本！它工作得很好。所以这个脚本通过标准的玛雅附加曲线工具将几条曲线组合成一条多形曲线，而不用关闭点！所以现在它看起来像：

import pymel.core as pm

#Get list of objects
shapeList = pm.ls(pm.listRelatives(c=True))
groupList = pm.ls(pm.group(em=True, n='Curve#'))
listAll = []
for obj in groupList:
    listAll.extend(shapeList)
    listAll.extend(groupList)

#Parent objects to one Curve
pm.select(listAll)
pm.parent(r=True, s=True)

#Clean scene
trans = pm.ls(tr=True)
parents = pm.listRelatives(pm.ls(), type='transform', p=True)
deleteList=[]
for obj in trans:
    if obj not in parents:
        deleteList.append(obj)
        print '%s, has no childred' %(obj)   

if len(deleteList) > 0: 
   pm.delete(deleteList)
